SYDNEY (AP) -- Rory McIlroy birdied the 18th hole to beat Adam Scott at the Australian
Open on Sunday, winning for the first time in 2013 and denying Scott the Triple Crown of Australian
golf.

McIlroy started the last round four shots behind Scott, but drew even when he eagled the
seventh and birdied the eighth.

Scott went a shot ahead with a birdie at the ninth. The pair then went shot for shot over the
back nine before the dramatic finish.

Scott's approach shot went over the back of the green and his chip went well past the hole,
with two putts bringing a bogey. McIlroy hit his approach to 10 feet and sank the putt to win by a
shot.

"I wanted to get a win and finally I've been able to get one," McIlroy said. "But more
satisfying than that is being able to take one of the best players in the world down the stretch
and come out on top.

"Adam is a phenomenal golfer, a great competitor and probably an even better guy and I feel a
bit sorry that I was the one that ruined the triple crown for him."

Scott was attempting to become only the second player after compatriot Robert Allenby in 2005
to win his country's Triple Crown by taking the Australian Open, Australian Masters and Australian
PGA titles in the same season.

He carried his form from the Masters and PGA tournaments into the Open, shattering the course
record with a 10-under 62 in his opening round.

He came into the final day at 16 under, with rounds of 62, 70 and 68, four shots ahead of
McIlroy, who was four ahead of the next closest challenger.

That, in effect, made Sunday's final round a shootout between the No. 2-ranked Scott and
Northern Ireland's McIlroy, who was the world's top-ranked player last year.

Scott was left to rue a series of missed birdie opportunities, failing to make six putts from
within 12 feet during his final round.

"Nothing was going my way on the greens today," Scott said. "I could have put this thing away
early on if the putter was behaving how it should have, how it did the rest of the week."

Both players took irons from the tee on the last hole and landed their shots adjacent to each
other on the fairway. Scott's approach landed ahead of the hole, but a bounce sent the ball flying
through the back of the green.

Rather than pitch and run back onto the green, Scott chose to give his chip some loft. It
failed to pull up, rolling onto the lower tier of the green and he did well to salvage a bogey.

McIlroy stood assessing his 10-foot putt during Scott's excursions. After Scott holed out,
McIlroy rolled in a slow putt that just made it to the hole.

"I didn't think it was going to unfold the way it did," McIlroy said. "It's hard not to feel
some guilt in the way I won it. Having a one-shot lead going into the last having it taken away
from you right at the very end, it's tough."

McIlroy finished with an 18-under 270. Scott finished six shots ahead of Australian John
Senden (11 under).

Senden and Australians Bryden MacPherson and Rhein Gibson, who tied for fourth at 9 under,
all qualified for next year's British Open.
